Errors in MLC NAND Flash can be classified into retention errors and program interference (PI) errors. While retention errors are dominant when the data storage time is greater than 1 day, PI errors are dominant for short data storage times. Furthermore these two types of errors have different probabilities of 0->1 or 1->0 bit flips. We utilize the(More)
In this paper, a novel accurate method for detection of copy-move forgery is proposed. The proposed method compresses digital image using Discrete Wavelet Transform (DWT) up to the certain desired level based on the image size. This reduced dimensional image is then divided into overlapping blocks of fixed size. These blocks are sorted using lexicographic(More)
This paper presents an adaptive controller with wavelet neural network tuner for a class of uncertain underactuated systems. Proposed scheme utilizes the concept of hierarchical structure error surface. Hierarchical structure is obtained by recursive coupling of error surfaces designed for individual subsystems. Error surface coupling is carried out such(More)
This paper presents an adaptive control strategy which combines the hierarchical control scheme with adaptive wavelet neural network for a class of multi-input multi-output (MIMO) underactuated systems with uncertain dynamics. Proposed scheme develops a systematic framework of the control components by applying hierarchical scheme to underactuated system.(More)
— Resource Management in wireless is concerned with a system in which the main aim is to make sure that a user/client can access the remote resources with as much ease as it can access the local resources. The basis of Resource Management is also resource sharing. The main goal of this project is to ease the sharing of resources among mobile users. We are(More)
Multimedia data are large in size as compared to the plain-text data. And hence to transmit them over a low-bandwidth communication channel, it needs to be compressed. In this paper, focus is on compressing gray-scale images. Here two types of compression techniques are explained: Lossy and Lossless. Within lossy techniques, there are three techniques:(More)
